T0 all whom trmajz/ concern.' i i y Be it k" own that l, Ina lV. KYLE, a citizen ofthe United States, residing at Mankato, in the county of Jewel and State of Kansas, have invented new and useful Improvements in Molds, of which the following is a specication;

The invention relates to molds, and `more particularly to the class of knock down forms for making concrete culverts, drains, conduits, or the like.

y The primary obj eet of the invention is the `provision of a form whereinV the top and sides thereof are separable, the top being sectional and having hinges connecting the same so that the parts of the mold can be readily and easily set up for use, and after the hardening of the cementitious material the said form can be easily and quickly removed without damage to the finished product. Y

Another object. of the invention is` the provision of a form of this character which is simple in construction, possessing few parts, readily and easily assembled and disiassenibled as the occasion requires, and also `one which is tl'ioro-ughly reliable and eflicient in its purpose and inexpensive in manufacture.

W ith these and other objects iii view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the clainihereunto appended.

ln the drawing Figure 1 is a perspective view of a mold or forni constructed in accordance with the invention. Fig. 2 is a vertical transverse sectional View througha conduit or culvert showing the mold in posi- `tion therein. Fig. 3 is a vertical transverse sectional view through the mold. Fig. 4L is a plan view of the top of the mold. Fig. 5 is a similar view, looking toward the opposite side.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

: Referring to the drawing in detail, the

form comprises a top A and sides B and C respectively, the top being formed of two sections aand G, which are of similar construction and are connected together through the medium of hinges 7, which are fastened to the outer faces of the sections, while at the outer longitudinal edges of these sections alie `Secured `keepers 8 which project beyond .the edges a predetermined distance, the said edges being inwardly beveled as `at 9 and likewise the side sections have longitudinal beveled edges 10. y y

Fixed at intervals to the inner face of the ,y section 5 of the top are transversely disposed straps or bars 11 which are adapted to eze tend over the section 6 when in alinemeiit with the section 5, while carried by the said section 6 are guide members 12 in which is slidably fitted a'lockingy bar 13, the same being formed at intervals with notches 14 which are adapted to aline with the free ends `of the bars 11 so that the same will pass therethrough to lie between the locking bar 13 and the section 6 whereby on the shifting of the bar 13 so that the notches will move out of alinement with the free ends of the bars 11 the section G `will be lockedin the saine plane with the section 5. The locking bar 13 at one end is formed with a loop or eye 15 which permits the manipulation thereof for moving it to locking or re` leasing position. In the assemblage of the top and side sections of the ferm the saine are positioned as shown in Fig. 2 of the drawing, and when the top is in such position the keepei's 3 will rest upon thebeveled uppermost edges of the side sections B and C `so that the cement body can be formed about `the form to provide a runway or lead. therethrough as shown. After the ceiiientitious material becomes hardened the locking bar` 13 is moved to bring the notches into aline-` nient with the free ends ofthe bars 11, and thereafter the sectionscan be folded outwardly, thus disengaging the keepers 3 from `the uppermost edges of the side sections, and

thereafter the side sections ai'e removed from the space formed by the forni. It is to be` understood that the sides B and C of the `inold are `held against moving inwardly `when said mold is set up by the use of any suitable` bracing means.

From the foregoing it is thought that the construction and mannei of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

Vhat is claimed is A. form of the class described comprising a top and side sections separable from each other, the said top being formed in two parts, hinges connectingl the two parts of the top to pei-init the folding thereof, keepers iot iio

carried by the two parts of the top and named bars for preventing folding of the adapted to engage the uppermost edges of parts of the top. 10 the side sections, bars xed to one part of In testimony whereof I aiX my signature the top and adapted to overle the other part in presence of tWo Witnesses.
